Gleitfett grades differ in their parameters.

Gleitfett I E10 and Gleitfett II E75 were supplied with the Carl Zeiss Jena micromanipulator.
The Gleitfett III E410 offered here was supplied with the Carl Zeiss Jena Neophot-21 microscope.

This MAY suggest (although I have no proof in the form of manufacturer documentation) that the lower numbers (I and II) and the lower values of the "E" parameter (E10 and E75) were intended for finer mechanisms - and may therefore have a lower viscosity, for example. The III E410 grease, with its high "E" value, was supplied with a heavy microscope built around massive mechanics - so it may well be thicker.

This grease can of course be used on microscopes from other manufacturers as well - a few are listed in the "compatibility" section, but that is by no means a complete list.

PZO logo and a circular illumination filter - the one offered here is colorless.

Some newer versions of the PZO Biolar microscope included a blue illumination filter mounted in the microscope base. This filter cut out the yellow color of the light emitted by the bulb, providing the user with a pleasant, near-white light.

Unfortunately, this filter is not replaceable, and when the light source is changed to a halogen or cold LED, the blue light filter becomes annoying, as the light color changes from white to blue.

If the user tries to remove the original light filter themselves, they often break either the filter or its black housing. This brings us to the point where it's worth having this part on hand - you can easily swap the blue filter for a colorless one.

NOTE - this part is originally heat-attached and held in place by melted plastic legs. After replacement, it's best to glue it in place.

This item fits the following versions of the Biolar PZO microscope:

- for phase contrast
- for various phase contrasts (positive, anoptral, amplitude, Zernike)
- for DIC
- for water immersion (e.g., Lomo)
- all for oil immersion (e.g., Leitz 10x Oil / 25x Oil / 40x Oil / 100x Oil)
- apochromatic for better color
- for polarization
- only high magnifications, e.g., for analyzing cell wall ornamentation (50x / 63x / 80x / 100x)
- for darkfield work (objectives with an iris diaphragm in the center)

maintenance (especially cleaning) of this element is required. Since PZO Biolar microscopes are 40-50 years old, it is now possible to find units without this cover, as it was lost over the years.

This metal cover also acts as a heat sink and dissipates heat from the bulb - this can sometimes be seen as discoloration on the inner surface of the metal. For this reason, replacing it with an element made of cardboard or plastic is a very bad practice.

Without this cover, contaminants can enter the optical light beam, the angled mirror, or the field diaphragm, which may, for example, cause diaphragm failure or deterioration of image quality.

Monocular microscope head for a fluorescence microscope
Model: PZO MNJ-4
Mounting method: dovetail, diameter 43 mm
Supported eyepieces: 23.2 mm
Mounted filter: OG1 / GG9
For microscopes: PZO Biolar FL and PZO MB-30 FL

Why are monocular microscope heads often used in fluorescence microscopy? Fluorescence microscopy (especially older designs) produces a relatively dark image, so it is beneficial for 100% of the light beam to reach a single eye. A binocular microscope head would split the light 50% to each eye, which could result in an image that is too dark.

The barrier fluorescence filter PZO OG1 / GG9 mounted under the microscope head protects the eyes from the harmful spectrum of fluorescence illumination.

Note - there is also a PZO GG9 fluorescence filter (also available in my catalog). It is important to select the correct filters for the appropriate applications.

The OG1 / GG9 filter is a separate element that can be detached from the microscope head. It is mounted under the microscope head in a dedicated slot provided for this purpose.

Model: APO-WI-F 70x1,23
Magnification: 70x
Numerical aperture: 1,23
Correction: Apochromat
Tube length: 160 mm
Focal length: 33 mm
Immersion: yes - water
Cover glass: yes - thickness from 0.10 to 0.20 mm
Markings: APO = Apochromat, WI = water immersion, F = phase contrast
Thread: RMS
Year of production: 1972

Note: to work in phase contrast technology you need a Lomo KF-4 condenser (you can see it in the database under number 00653).

This is a professional microscope objective with a very wide range of applications. The main features that make this objective exceptional:
- water immersion is preferred by many users over oil immersion
- very high numerical aperture, allowing the objective to produce a high resolution image
- cover glass thickness correction ring

Standard biological objectives are designed to achieve the best image quality when the specimen is located under a cover glass with a thickness of 0.17 mm (hence the marking on objectives such as 160/0.17). Unfortunately inexpensive cover glasses often do not undergo strict production control and a single package may contain cover glasses with thicknesses of 0.14 mm or 0.19 mm, which reduces observation sharpness.
Thanks to the built-in cover glass thickness correction ring (abbreviated CGTCR, CGCC or CGCR) the objective can be adjusted for every specimen so that it operates optimally. This works even when the actual thickness of the cover glass is unknown, because the effect is simply visible and the adjustment can be done "by eye".

Although this objective is a so-called "short" objective, meaning with a parfocal length of 33 mm, after adding a 12 mm adapter (you can see it in the database under number 99140) it can be used with newer microscopes designed for objectives with a parfocal length of 45 mm.

The Lomo company produced adapters specifically for these objectives (converters) from RMS thread to M27 thread, which makes them a very attractive option for installation in modern Zeiss Axio series microscopes.

eyepiece contains two lines in the field of view used for adjusting DIC interference fringes, but this is the only difference compared to an otherwise identical eyepiece used for adjusting phase contrast. Therefore it can be used:
- for adjusting DIC
- for adjusting phase contrast
- for observing the iris diaphragm
- for observing the filament when setting illumination according to the Köhler standard

This is one of those microscope elements for which many different names are used. Among others:
- phase telescope
- phase contrast telescope
- phase alignment telescope
- phase adjustment telescope
- phase centering telescope
- phase contrast centering telescope
- phase contrast alignment telescope
- phase contrast adjustment telescope
- centering telescope
- condenser centering telescope
- condenser alignment telescope
- condenser adjustment telescope
- alignment telescope
- adjustment telescope
- inspection telescope
- aperture viewing telescope
- back focal plane viewing telescope
- auxiliary microscope

ring that allows correction of the vision defect of one eye and proper adjustment of image sharpness. The right eyepiece prism is integrated together with the tube.

Basic parameters:
- Type: tube with diopter correction ring
- Supported eyepiece diameter: 23.2 mm
- Included: right eyepiece prism
- For head model: PZO MND-6, both for models with black and with white housing.

This repair part (service element / replacement part) comes from a binocular head PZO MND-6 which was originally mounted on the microscopes:
- PZO Biolar DIC
- PZO Biolar B

However, because the PZO MND-6 head has a standard mounting interface typical for PZO microscopes (that is a dovetail mount with a diameter of 43 mm), this head can also be found mounted on other PZO microscopes such as:
- Studar
- MB-30

Additional information: the fluorescence microscope PZO Biolar FL was originally sold with a mono head (monocular head) - however the PZO MND6 head also fits this microscope model.

Hinweis - this tube with prism DOES NOT FIT heads that were originally sold with PZO Studar microscopes, even though these heads look very similar. Of course if a head from the Biolar model was mounted on a Studar microscope (because it fits), then this tube will be compatible, because it is a repair element for the HEAD and not for a specific microscope model.
